STEP 2. Measure the power supply voltage at oil feeder control valve oil pressure switch connector.
(1) Disconnect the oil feeder control valve oil pressure switch connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal OCVP line and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 4. Go to Step 3.
